cds-question@unistra.frmultiple-starssolar-system-planetsradial-velocityWe report the discovery of a new stellar companion in the KOI-13 system. KOI-13 is composed of two fast-rotating A-type stars of similar magnitude. One of these two stars hosts a transiting planet discovered by Kepler. We obtained new radial velocity measurements using the SOPHIE spectrograph at the Observatoire de Haute-Provence that reveal an additional companion in this system. This companion has a mass of between 0.4M_{sun}_ and 1M_{sun}_ and orbits one of the two main stars with a period of 65.831+/-0.029-days and an eccentricity of 0.52+/-0.02.2012A&A...544L..12Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/544/L12CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/528/A63 : Velocitometry transit of KOI-428b (Santerne+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/544/L12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/544/L12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/544/L12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/544/L12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/544/L12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/544/L12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/544/L12/table1SOPHIE radial velocity datarecnoRecord number assigned by the VizieR team.
